Este es el código con el que se recorre la tabla y deberia devolver los registros, pero solo lee 1 y lo repite 5 veces. En la tabla tengo cargados 2 registros. Además probé con otras tablas y hace lo mismo.
Código PHP:
<?php
$conn = new conection();
$rs = new RecordSet($conn);
$sql="SELECT * FROM `novedades`";
$novedades = $rs->get_object($sql);
foreach($novedades as $clave=>$valor){
echo $novedades->titulo;
echo $novedades->texto;
}
?>
